Authorize the role permission settings to add the following button @ Html to SysUser's Index. toolButton ("btnAllot", "icon-share", "Assign role", perm, "Allot", true) We need to pop up the selection window for all roles to check and save. You should have thought of this, so first set the view on the pop-up interface, I named GetRoleByUser, so I added the following three methods to SysUser to copy the Code # region sets the user role [SupportFilter (ActionName = "Allot")] public ActionResult GetRoleByUser (string userId) {ViewBag. userId = userId; ViewBag. perm = GetPermission (); return View ();} [SupportFilter (ActionName = "Allot")] public JsonResult GetRoleListByUser (GridPager pager, string userId) {if (string. isNullOrWhiteSpace (userId) return Json (0); var userList = userBLL. getRoleByUserId (ref pager, userId); var jsonData = new {total = pager. totalRows, rows = (from r in userList select new SysRoleModel () {Id = r. id, Name = r. name, Description = r. description, Flag = r. flag = "0 "? "0": "1 ",}). toArray ()}; return Json (jsonData);} # endregion [SupportFilter (ActionName = "Save")] public JsonResult UpdateUserRoleByUserId (string userId, string roleIds) {string [] arr = roleIds. split (','); if (userBLL. updateSysRoleSysUser (userId, arr) {LogHandler. writeServiceLog (GetUserId (), "Ids:" + roleIds, "success", "Assign role", "user settings"); return Json (JsonHandler. createMessage (1, Suggestion. setSucceed), JsonRequestBehavior. allowGet);} else {string ErrorCol = errors. error; LogHandler. writeServiceLog (GetUserId (), "Ids:" + roleIds, "failed", "Assign role", "user settings"); return Json (JsonHandler. createMessage (0, Suggestion. setFail), JsonRequestBehavior. allowGet) ;}} copy the code GetRoleByUser. In the pop-up view, GetRoleListByUser obtains the role based on the selected user and displays the selected role status (Stored Procedure Implementation) copy the Code USE [AppDB] GO/****** Object: StoredProcedure [dbo]. [P_Sys_GetRoleByU SerId] Script Date: 02/21/2014 11:17:38 ******/SET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOCreate proc [dbo].

[P_Sys_UpdateSysRoleSysUser] @ roleId varchar (50), @ userId varchar (50) AS -- Update the BEGIN insert into SysRoleSysUser (SysRoleId, SysUserId) values (@ roleId, @ userId) END: the statement used to copy the Stored Procedure Code is short. If it is made into linq, It is not changeable. Therefore, I wrote the stored procedure. You can refer to the logic to make a program. SysBLL adds the following method to copy the code public IQueryable <P_Sys_GetRoleByUserId_Result> GetRoleByUserId (ref GridPager pager, string userId) {IQueryable <strong> queryData = sysUserRepository. getRoleByUserId (db, userId); pager. totalRows = queryData. count (); queryData = sysUserRepository. getRoleByUserId (db, userId); return queryData. skip (pager. page-1) * pager. rows ). take (pager. rows);} public bool UpdateSysRoleSysUser (string userId, string [] roleIds) {try {sysUserRepository. updateSysRoleSysUser (userId, roleIds); return true;} catch (Exception ex) {ExceptionHander. writeException (ex); return false ;}} copy code SysRepository Add the following method copy code public IQueryable <P_Sys_GetRoleByUserId_Result> GetRoleByUserId (DBContainer db, string userId) {return db. p_Sys_GetRoleByUserId (userId ). asQueryable ();} publ Ic void UpdateSysRoleSysUser (string userId, string [] roleIds) {using (DBContainer db = new DBContainer () {db. p_Sys_DeleteSysRoleSysUserByUserId (userId); foreach (string roleid in roleIds) {if (! String. isNullOrWhiteSpace (roleid) {db. p_Sys_UpdateSysRoleSysUser (roleid, userId) ;}} db. saveChanges () ;}} copy the code and add the interface method by yourself. Then enter the GetRoleByUser view code to copy the code @ using App. admin; @ using App. common; @ using App. models. sys; @ {ViewBag. title = "Set User Roles"; Layout = "~ /Views/Shared/_ Index_LayoutEdit.cshtml "; List <permModel> perm = (List <permModel>) ViewBag. perm; if (perm = null) {perm = new List <permModel> () ;}< div class = "mvctool bgb" >@html. toolButton ("btnSave", "icon-save", "save", perm, "Create", true) </div> <div class = "pd3"> <table id = "UserList"> </table> </div> @ * Jqgrid * @ <script type = "text/ javascript "> $ (function () {$ ('# userlist '). datagrid ({url: '/SysUser/GetRol EListByUser?
